Grinding your teeth day and night could come back to haunt you in the long run. You can always ask your dentist to get you a custom night guard. The BruxRelief Biofeedback Therapy device might also help. The KITT Basic and KITT Plus come with a device that attaches to your jaw with disposable EMG sticky pads. The device monitors your jaw muscles for any grinding activity. The detachable earbud alerts you during the night but doesn’t disturb your partner.
The KITT Plus communicates with your smartphone to enable you to easily keep track of your progress. More info is available here.
